Abstract (en)
The lighting device comprises: a plurality of light sources with varied light-emission spectra; photodetection means which determine at least one characteristic of the ambient spectrum; feedback means which compare said at least one characteristic of the ambient spectrum with a corresponding characteristic of a preconfigured spectrum and modify the emission of at least one of said sources so as to minimize the difference between the characteristic of the ambient spectrum detected and the characteristic of the preconfigured spectrum. <IMAGE>
